I went around the trunk with a hatchet and a spray bottle (about 1 ml/spray = the usual) and did hack and squirt about every 4-6 inches. Unfortunately, I cannot remember the name for sure, but I think it was Milestone (aminopyralid).

Finally in HPP
Yes, it is Milestone. It is expensive but for killing junk trees one bottle is a lifetime supply for most people. It only takes like 3CC to kill the biggest albezias though I strongly recommend a follow-up application for the really big ones. Here's a video on how to use it:
Dr. James Leary, CTAHR Invasive Weed Specialist, conducts field trials at Maunawili Experiment Station, Oahu, targeting the invasive tree Albizia (Falcataria moluccana; syn. Albizia moluccana, Albizia falcata, Albizia falcataria, Adenanthera falcataria, Paraserianthes falcataria). Using Milestone® VM (active ingredient: aminopyralid), he researches two application methods: drill application vs. frill cut.
A second trial compares the effects of three different herbicides on albizia: 2,4-D® (active ingredient: 2,4-Dichlorophenol), Garlon®4 Plus (active ingredient: triclopyr), and Milestone® VM (active ingredient: aminopyralid).
Preliminary results are shown after 1 week, 2 weeks, and 5 weeks. Partial funding provided by the USDA via the RREA and TSTAR programs.

Just one request, if you use Milestone don't take any of the tree waste to the green bins for disposal because it can mess the mulch up and ruin people's gardens. Although Milestone is labeled for use on pasture with grazing animals there have been ill effects when people following the wait times etc put manure into their compost- and that was with using Milestone in proper dilution. For tree killing it's used off-label at full strength.
